I've noticed, after playing on a server for a week, that the Pike AI, which was once perfectly fine (loved the bonemeal river we settled next to!), is now not very functional. Pikes will swim around in circles trying to get a salmon item, or just clump up in a giant ball.

This is not a fluke either, the server has been restarted, I've gone to other rivers or lakes with Pikes, I've thrown fish at them, I've taken the items they were trying to get, and the Pike AI seems to continuously get stuck.

Ok, never mind this issue. This was because mob griefing was off.
